IMPROVEMENT IN CLASPS FOR ATTACHING STRAPS T0 HORSE-BLANKETS.

Specification forming part of Letters Patent No. 187,888, dated February27, 1877; application filed August 30, 1875.

To all whom it may concern:

Be it known that I, ANDREW Z. NEFF, of Amsterdam, in the county ofMontgomery and State of New York, have invented a new and usefulImproved Device for Attaching and Detaching Straps to Horse Blankets 5and 1 do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,making part ot' this specication, in which- Figure 1 is a plan of one ofthe concaveconvex pieces, showing the perforations and the loop or ringattached to and forming one and the same piece by casting together. Fig.2 is a vertical sectional view through the line a: w of Fig. 1,showing,when attached to a piece of fabric, the plate A, having the loopor ring m and the central hole to receive the screw, all cast in one andthe same piece, the oppo site plate A', with the nut o and the screw D.

The nature of my invention consists in the use of circular disks ofequal diameters, each of which is made concave, and provided withperforations, substantially as shown in the drawings. One of these disksis provided in the center, on the concave or inner side, with a nut, o,cast upon and with the same piece, said nut being threaded to receive ascrew.

The other disk or concave plate is provided with a loop or ring at oneside, as shown, (see Fig. 1,) to receive the strap or snap attached to astrap, and having a central hole to receive a screw, the whole beingcast together rigid in one and the same piece.

The concave edges of each disk or plate is rounded, so as not to presenta sharp corner or cutting-edge, which would bite or chafe by use thefabric to which it was attached.

ln using the rigid cast clamping-plates A and A', they are placedopposite each other, upon the two sides of the fabric E, with theirconcave sides inward, as seen in Fig. 2, and a screw, D, is insertedthrough the central hole in the plate A, and passed through the fabricE, and screwed into the threaded nut of the opposite plate A'.

By this means the two plates are clamped tightly together upon thecloth, and thus take a lirm hold without injury thereto.

After the plates are thus secured by the screw D, a coarse thread orcord, or a simple string of lacing-leather, is passed alternatelythrough the perforations in each plate, and the fabric and the endsfastened, thereby preventing the loss of' one or each ot' a pair in casethe screw D should become unscrewed and fall out.

The advantages of my invention consist in making each concavo-convexplate of castirou, casting therewith in one piece the nut o and plateA', and casting the ring or loop m and plate A all in one and the samepiece, each being provided with the perforations c, so that they may bestitch-ed at pleasure to prevent losing.

By this mode of manufacture or construction the clamps can be morecheaply furnished to the public, and are particularly adapted to receiveand apply to my horse-blanket adjuster, (Patent No. 124,506, dated Marchl2, 1872,) to which this is supplementary.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

The combination of the clamping-plate A, having the loop or ring m andperforations c, cast in one and the same piece, with the plate A',having the corresponding perforations c and the screw-threaded nut o,adapted to be united by the screw and lacing, substantially as and forthe purposes specitied.
